At present, various techniques have been proposed to deal with the problem of sound input, such as solving the sound feedback, wind cut, noise, gain problem. The technology of the microphone has matured to a stage. This is a component that can't be lacked in communication devices. Different sounds will have different sound waves. The sound through the microphone can be converted into sound waves. The communication device converts the sound waves into data. Processing, such as transmitting sound to the conversation side. SUMMARY OF THE INVENTION The inventor of the present invention thinks that sound waves represent different orientations (such as the front-I) and the input of the button and the microphone and the analysis of the radio and control unit generate corresponding position signals or control positions to provide different In the past, the device was used. • One of the objects of the present invention is to provide a less expensive pointing device for the purpose of providing a low cost orientation. Still another object of the present invention is to provide a pointing device for inputting an azimuth or control signal by sound waves. Thus, the pointing device of the present invention comprises a contact surface on which an object moves, a sound generated by moving the object on the contact surface, a microphone and a control unit that are sent to the sound wave signal; The two-unit unit analyzes the sound wave signal when the sound wave signal is received to determine that: the body moves the position on the contact surface to generate a position signal to use the microphone to collect the sound and the user can use the object to contact the surface. The movement on the corresponding to the cursor movement on the control window. Moreover, the microphone of the pointing device of the present invention can be a matrix type microphone, so that the control unit can analyze the moving position of the object on the contact surface by generating the position of the sound wave in sequence to generate the corresponding position signal. Furthermore, the pointing device of the present invention can plan a plurality of regions of different acoustic waves on the contact surface, so that the control unit can use different sound waves to determine the moving region of the object on the contact surface, thereby inferring the moving direction. Thus, the pointing device of the present invention can be achieved at a lower cost. In addition, the regions of the contact surface of the pointing device of the present invention may be different materials or nicks, and in addition to generating different sound waves, the user may be provided with different touches. Further, the present invention refers to the control unit of the Xiaozhong control unit. The pressing action corresponds to the characteristic data of the sound wave, and the control unit further determines that the object performs the pressing action to generate a control signal when receiving the sound wave signal conforming to the characteristic data from the microphone. The above and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figure 1, the preferred embodiment of the pointing device of the present invention comprises a contact surface η 克 风 wind 12 and a control unit ??? The pointing device of the embodiment is suitable for being mounted in an electronic device, such as a mobile phone, a notebook computer, a personal digital assistant, etc., in the embodiment, the pointing device is installed in a mobile phone as an example to illustrate 'under In the text, the term mobile phone is used interchangeably with the electronic device-word. Of course, the pointing device of this embodiment may also be a separate component, and is not limited to those disclosed in the embodiment. The contact surface 11 is for moving an object such as a finger thereon. The microphone 12 system converts the sound generated by moving the object on the contact surface 11 into an acoustic signal to the control unit it13. The control unit S 13 of the embodiment has an analogy to 7 200811691 digital conversion state 131 and a digital signal processor I" 'the analog to digital converter 131' receives the acoustic wave signal and digitizes it and transmits it to the digital position. The signal processor 132 and the digital signal processor 132 use the digitized audio signal to analyze the object system to perform a pressing action or azimuth movement on the contact surface to generate a control signal or a position signal to the mobile phone. First, when The user makes a pressing action on the contact surface n, and the whole action can include three steps: the object is pressed, the object is stationary, and the object is lifted. As shown in FIG. 2, the sound signal generated by the microphone 12 is pressed when the object is pressed. Correspondingly, a surge 121 is generated, and the sound wave stops when the object is stationary.

In this way, the digital signal processor 132 only needs to pre-store the waveform data of the corresponding acoustic wave signal according to _, and refers to the characteristic data after the sound wave is digitized, and when the digital sound wave data is received, it can be correspondingly determined whether it is a pressing action. . When the object moves up, down, left or right on the contact surface U, there is no change in the ear wave axis as shown in FIG. In order to assist the digital signal processor to analyze the moving orientation of the object on the contact surface 11, the microphone 12 of the embodiment may be a matrix microphone, which refers to a plurality of microphones arranged in a matrix array, so that the digital signal processing n 132 can be utilized. The sound signals of different microphones are used to analyze the object on the contact surface 11 (4) to be pure, in order to generate a position signal to the mobile phone. The above-mentioned mobile signal, τ shift signal, left shift signal and right shift signal S can also be utilized. The special design of the surface 〗 1 to the object in contact with a different area of the day ^ can correspondingly produce different sound waves, so only need to match the octopus wind 12 and occupy less use area to achieve the purpose of moving position judgment 200811691. In detail, as shown in FIG. 4, four upper areas 111, a lower area 112, a left area 113, and a right area 114 are planned on the contact surface u, and a sound hole 115 is provided in the center of each area m~114, and the microphone is arranged. ^ is located directly below the sound hole 115 to increase the radio effect. Of course, the sound receiving hole 115 can also be a receiving slot, and the microphone U can be directly placed in the sound receiving hole 115. Each of the regions 111-114 uses different nicks to generate different sound waves, and the upper region 111 is provided with a plurality of transverse scribes parallel to each other to generate an acoustic signal as shown in FIG. 5 when the object moves in the upper region 111; a plurality of longitudinal longitudinal indentations parallel to each other, such that the object generates an acoustic signal as shown in FIG. 6 when the object moves in the lower region 112; and the left region i丨3 sets a plurality of oblique indentations extending from the upper left to the lower right for the object to When the left area 113 moves, the sound wave signal of FIG. 7 is generated; the right area 114 sets a plurality of oblique marks extending from the upper right to the lower left to generate an acoustic wave signal as shown in FIG. 8 when the object moves in the right area 114. In this way, the regions lu~114 can generate different acoustic signals when the object moves thereon, and the digital signal processor 132 pre-stores the characteristic data of the acoustic signals digitized in each region. In order to provide a sufficient amount of acoustic signals to the digital signal processor 132 to analyze the moving position digital number processing Is 13 2, when analyzing the digitalized acoustic signals from the analog to digital processor 131, the acoustic signals are sequentially identified from the upper region in and the lower region. When the 112 is generated, the corresponding mobile signal is generated, and the acoustic signal is sequentially identified. When the lower region 112 and the upper region lu are generated, an upper motion is generated, and the acoustic signal is sequentially identified by the left region 113 and the right region 114. At the beginning, a right shift signal is generated, and the sound signal is sequentially identified to generate a left shift signal when the right region Π4 and the left region 113 are generated, and the digital signal 200811691 says that the benefit 132 can be calculated according to the sound wave signal. The moving speed and the inter-turn length are added to the azimuth signal (referring to the left, right, up, and down signals) by pushing the distance moved by the cursor on the window. Thus, when the user wants to move the cursor down, only the object moves to the lower area 112 in the upper area ill, and the digital signal processor 132 correspondingly generates a downward nickname to the mobile phone; and when the user wants the cursor When the soil moves, it only needs to move the object to the upper area 112 to the upper area m, the digital signal processor

Telephone, when the user wants to move the cursor to the right, the object moves to the left area ιΐ3 in the left area 113, and the cursor on the window is moved to the right by the digital signal processor 132. When the cursor moves: to the user's option to click on the image, the user only needs to perform a pressing action on the receiving hole 115, and the digital signal processor will generate a control signal to the mobile phone. This option can be selected to perform the next job. Moreover, each of the regions lu to 114 of the present embodiment may be replaced by different materials (e.g., leather, cloth, etc.) to generate different sound waves. Furthermore, although the upper and lower left and right displacements are planned in the four regions (1) to 114 in this embodiment, those skilled in the art know that the number of regions (1) to m can be adjusted according to the actual design azimuth demand, such as an area. The number is increased by eight and should not be limited to those disclosed in the embodiment. In addition, since the pointing device of the embodiment is integrated in the mobile phone, and the mobile phone itself has a digital signal processing-and analog-to-digital converter, the digital device of the pointing device of the present embodiment 10 is analogous to the processor 132 of 200811691. The digital converter 131 can apply the components of the mobile phone itself, and only needs to cut the acoustic signals of the respective regions lu~114 and the feature data of the pressing action into the digital signal processor 132 and add the aforementioned analysis to identify the private sequence to the digital position. $ i32 is fine, without the need to set up additional components to effectively reduce costs. According to the foregoing, the pointing device of the present invention uses the microphone 12 to pick up sound waves generated by the movement or action of the object on the contact surface 11, and can generate different sound signals by using a matrix microphone or different regions to make the control unit π 13 The corresponding orientation signal is generated by analyzing the moving direction of the object on the contact surface n. Moreover, since the cost of the microphone 12 is low and the volume is very small, the pointing device of the present invention can achieve the effects of low cost and small volume. The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
